    摘要: In one embodiment, a semiconductor device is provided that includes a gate structure present on a channel portion of a fin structure. The gate structure includes a dielectric spacer contacting a sidewall of a gate dielectric and a gate conductor. Epitaxial source and drain regions are present on opposing sidewalls of the fin structure, wherein surfaces of the epitaxial source region and the epitaxial drain region that is in contact with the sidewalls of the fin structure are aligned with an outside surface of the dielectric spacer. In some embodiments, the dielectric spacer, the gate dielectric, and the gate conductor of the semiconductor device are formed using a single photoresist mask replacement gate sequence.

    摘要: A method for semiconductor fabrication includes patterning one or more mandrels over a semiconductor substrate, the one or more mandrels having dielectric material formed therebetween. A semiconductor layer is formed over exposed portions of the one or more mandrels. A thermal oxidation is performed to diffuse elements from the semiconductor layer into an upper portion of the one or more mandrels and concurrently oxidize a lower portion of the one or more mandrels to form the one or more mandrels on the dielectric material.
